Product FAQs
9 answersWhat does the SA suffix indicate on the HGL36050SA catalog number?
The SA suffix means this circuit breaker includes a factory-installed 120VAC shunt trip accessory. This allows the breaker to be tripped remotely for emergency shutdown or control applications.
What is the short-circuit interrupting rating for this breaker at 600VAC?
While rated for 65 kAIC at 240VAC and 35 kAIC at 480VAC, the HGL36050SA has a maximum interrupting rating of 18 kAIC when applied in 600VAC systems.
Can the HGL36050SA be installed in a Square D I-Line panelboard?
No. This is a unit-mount, feed-thru circuit breaker equipped with line and load lugs. It does not have the plug-on jaw connections required for I-Line distribution panelboards.
What type of trip unit does the HGL36050SA use?
It is equipped with a fixed thermal-magnetic trip unit. This provides standard long-time overload protection and instantaneous short-circuit protection (LI functions).
Which standalone enclosures are compatible with this breaker?
This unit-mount breaker fits into Square D PowerPacT H-frame enclosures, such as the HD100S (NEMA 1), which is designed for 3-pole breakers up to 100 amps.
Does this breaker provide ground-fault protection?
No. The HGL36050SA is a standard thermal-magnetic breaker. It does not feature integrated equipment ground-fault protection (LSIG) or personnel earth-leakage protection.
Is the shunt trip accessory field-replaceable?
The 120VAC shunt trip is factory-installed internally behind the accessory cover. While PowerPacT H-frame accessories can be accessed in the field, this specific catalog number is shipped with the shunt trip already wired and seated in the left accessory compartment.
What is the maximum frame size of the PowerPacT H series?
The PowerPacT H-frame series has a maximum continuous current frame size of 150 amps, though this specific breaker is factory-calibrated for a 50-amp continuous load.
Is the HGL36050SA rated for direct current (DC) applications?
Yes. In addition to its AC ratings, this thermal-magnetic breaker is rated for use in DC systems up to 500VDC, where it provides a short-circuit interrupting rating of 20 kAIC.
